This drama got into high gear in its second season with an Emmy-nominated performance by Ethel Waters as a dying blues singer in "Good Night, Sweet Blues," Robert Redford as the college-educated son of a Polish mill worker in "First Class Mouliak," Robert Duvall as a heroin addict in "Birdcage on My Foot," Lee Marvin as a French chanteuse's violently possessive manager in "Mon Petit Chou," Julie Newmar as a free-spirited biker in "How Much Is a Pound of Albatross?" Martin Sheen and James Caan as former gang members trying to go straight in "And the Cat Jumped Over the Moon," and Burt Reynolds as a small-town hood in "Skinny Kid."

Yale-educated Tod Stiles (Martin Milner) and Hell's Kitchen-bred Buz Murdoch (George Maharis) prove that the journey is more important than the destination as they crisscross America in search of themselves and helping others find purpose in their lives. The original road-trip drama, each episode featured a new location, intriguing characters, compassionate stories, top-drawer writing by Oscar winner Sterling Silliphant, a catchy theme song by Nelson Riddle, a classic car (1960 powder-blue Corvette), and one of the most impressive inventories of guest stars to ever populate a TV series.
